By substantially closing the mounting recess 1 to which the power feeding wiring 11 is distributed from the outside, it is possible to reliably prevent the spread of fire to the power feeding wiring 11.

Here, the substantial blockage by the blockage wall portion 10 of the housing 4 means that the inside of the mounting recess 1 is completely closed by abutting against the open end of the mounting recess 1, and an appropriate clearance is provided at the opening end of the mounting recess 1. It also includes the state of being set and approaching.

Further, by locking and holding the power feeding wiring 11 in the wiring holding recess 12 formed on the outer wall of the housing 4, the power feeding wiring 11 does not enter the irradiation region of the light emitting body 5 and generate a shadow. Furthermore, wiring workability is also improved.

Further, the light emitting body 5 can be arranged at the innermost part of the housing appropriately separated from the light emitting opening 3 in a posture in which the optical axis is inclined toward the center of the passage with respect to the mounting recess 1.

Also, using the above handrail Kasagi,
The metal lower Kasagi 13 placed at an appropriate height on the side of the aisle,
Above the lower cap tree 13, there is an upper cap tree 14 made of the handrail cap tree arranged along the lower cap tree 13.

In the present invention, the handrail device is formed by arranging the upper and lower caps 13 side by side, the upper caps 14 are formed of a nonflammable material, and the lower caps 13 are formed of a metal material to ensure nonflammability. To.

When the upper cap tree 14 is made to emit light and the lower cap tree 13 located below the lower cap tree 13 is made of a metal material in consideration of nonflammability, the lower cap tree 13 is exposed to the irradiation light from the upper cap tree 14 and the upper stage feels dazzling. In the present invention, the housing 4 of the cap tree 14 is provided with a guide wall 15 that does not include the lower cap tree 13 and guides the irradiation region from the light emitting body 5 to the irradiation region biased toward the center of the passage. Since the direct irradiation from the illuminant 5 is prevented, the glare is not felt.

It is sectional drawing which shows the handrail apparatus of this invention. It is sectional drawing of the bracket connection part of FIG. It is a figure which shows the handrail cap tree of this invention, (a) is a sectional view, (b) is an exploded view of a lighting unit, (c) is an exploded view of a handrail cap tree. It is an exploded perspective view of a handrail Kasagi. It is explanatory drawing which shows the connection state of the LED unit and the power supply wiring.

FIGS. 1 and 2 show a handrail device using the handrail cap tree of the present invention. The handrail device of this example is formed as a wall handrail in which two upper and lower caps are arranged along the wall surface as the installation base 16.

In this example, the upper and lower caps 13 and 14 are fixed to the wall surface 16 via the brackets 17, respectively, but it is also possible to fix the upper and lower caps 13 and 14 to the same bracket. It is also possible to provide the handrail caps via the brackets provided on the columns.

As shown in FIG. 2, the bracket 17 is a pipe body bent into an L-shape in a side view, and is fixed to an anchor 18 driven into the wall surface 16 by using a screw 18a or the like. A support seat member 19 is press-fitted or connected to the upper end of the bracket 17 using a fastener, and upper and lower caps 13 and 14 are fixed on the support seat member 19.

In order to improve the nonflammability of the entire handrail device, the bracket 17 and the upper and lower caps 13 and 14 are formed of a metal material, and the lower caps 13 are formed in the shape of a cylindrical hollow pipe.

As shown in FIG. 3 and below, the upper cap tree 14 has a long stainless steel cap tree main body 2 and a lighting unit 7 fixed to a mounting recess 1 formed in the cap tree main body 2.

The mounting recess 1 is recessed downward in a notch shape based on the mounting state on the mounting base 16, and is used as a connecting portion to the bracket 17. As shown in FIG. 2, the mounting recess 1 is fixed to the bracket 17. The support seat member 19 and the ceiling wall of the mounting recess 1 are connected by bolts 21 via a connecting piece 20 fitted in the mounting recess 1.

On the other hand, the lighting unit 7 has a housing 4 formed in a rail shape by an extruded aluminum profile, and an LED unit as a light emitting body 5.

As shown in FIGS. 3, 4, and 5, the LED unit 5 is formed by mounting a plurality of LEDs 5b on a mounting substrate 5a such as a flexible printed circuit board at predetermined intervals, and is entirely covered with a transparent protective tube 5c. There is. Further, to the mounting board 5a of the LED unit 5, a branch wiring branched by a splice terminal or the like is connected to a power supply wiring 11 connected to a commercial power source, and drive power is supplied.

As shown in FIG. 3, the housing 4 has a light projecting opening 3 continuous in the longitudinal direction at a position appropriately spaced from the light emitting body holding piece 4a arranged at the innermost part, and holds the light emitting body. A pair of guide walls 15 are arranged between the piece 4a and the side edge of the light projecting opening 3.

The LED unit is fixed to the light emitting body holding piece 4a by an appropriate means such as adhesion, and the light emitting body holding piece 4a is attached to the Kasagi main body 2 with the optical axis (OA) of the LED (the axis that maximizes the amount of projected light). It is set so as to be tilted by a predetermined angle (θ) with respect to the opening direction of the recess 1, that is, the vertically downward direction.

Further, in the guide wall 15, the irradiation range of the maximum light amount range around the optical axis (OA) of the irradiation light from the illuminant 5 avoids the lower Kasagi 13 and the passage side is the irradiation area, as shown in FIG. Is set to. As a result, since it is possible to avoid irradiation of the lower Kasagi 13 with a large amount of light, it is possible to reduce the glare due to the reflected light from the lower Kasagi 13, and it is possible to illuminate the passage brightly. It is possible to prevent the irradiation light from the illuminant 5 from being directly applied to a short pedestrian.

Further, the light projection opening 3 is substantially located at the open end edge position of the mounting recess 1 with the lighting unit 7 fixed to the mounting recess 1, and is a glass lid having a light diffusing plate 9 attached to the upper surface thereof. It is blocked by 6. An inward flange 4b is projected from the lower end of the guide wall 15 of the housing 4 to hold the glass lid 6. The light diffusing plate 9 scatters the emitted light from each LED 5b of the LED unit 5 to prevent the generation of high-luminance spots corresponding to the LEDs 5b on the floor surface.

Since the light projecting opening 3 is closed by the nonflammable glass lid 6, the region inside the unit surrounded by the light emitting body holding wall 4a, the guide wall 15, and the glass lid 6 is blocked from the outside. In this state, the spread of fire to the LED unit 5 is surely prevented, and further, the light diffusing plate 9 formed of synthetic resin or the like is protected by the glass lid 6, so that the overall nonflammable performance can be improved.

Further, a closed wall portion 10 is formed at the lower end of the guide wall 15 of the housing 4 so as to project outward in a flange shape. The closed wall portion 10 substantially shields the area outside the unit inner region of the housing 4 from the external space of the handrail cap tree inside the mounting recess 1 by the tip edge approaching the inner wall surface of the open end edge of the mounting recess 1. Then, the power supply wiring 11 for supplying power to the LED unit 5 described above is locked, held and laid in the wiring holding recess 12 formed in the area, to be exact, the outer wall portion of the guide wall 15.

By laying the power supply wiring 11 outside the unit inner region through which the light emitted from the LED 5b passes, it is possible to prevent shadows from being generated by the power supply wiring 11, and the wiring holding recess 12 is provided. Therefore, as will be described later, it is possible to effectively prevent the power feeding wiring 11 from being caught when the lighting unit 7 is mounted.

The lighting unit 7 configured as described above is mounted on the Kasagi main body 2 by housing 4 on the elastic locking piece 8b of the unit locking member 8 previously fixed to the ceiling wall of the mounting recess 1 using screws 8a. It is performed by elastically locking the locking claw 4c of the above. The unit locking member 8 in this example is made of a synthetic resin material in consideration of the fact that the inside of the mounting recess 1 is isolated from the external space and that it has a high elastic deformability.

The lighting unit 7 has substantially the same longitudinal dimension as the Kasagi main body 2, and as shown in FIG. 5, power is supplied to each LED unit 5 at the connecting portion of the Kasagi main body 2 by the connecting joint 22. Will be.
